Why is %29 in a URL Encode to ) During a Request?

Hi Suraj_Ncircle 
While encoding the entire URL using Uri.EscapeDataString in PQ is problematic because Web.Contents expects a valid absolute URL and may not properly handle fully encoded URLs.
However, we can work around this by constructing the request in a way that ensures encoding remains intact.
Manually encoding the entire URL:
***************************************************************
let
BaseUrl = "https://cdn.Domain.com/dXJuOmFkc2sud2lwcHJvZDpmcy5maWxlO_dmVyc2lvbj0x/output/Resource/3D%20View/2_%2...",
Cookies = "your_cookie_data",
EncodedUrl = Uri.EscapeDataString(BaseUrl), // Encode the entire URL
QueryResponse = Web.Contents(EncodedUrl & Cookies, [Headers=[#"Accept"="application/json"]])
in
QueryResponse
